Anubis is a protective measure implemented by the administrator of this website to safeguard against AI companies aggressively scraping its resources, which can lead to downtime and inaccessibility for all users. It employs a Proof-of-Work scheme similar to Hashcash to make individual loads ignorable but collectively expensive for mass scrapers. Anubis aims to allow more time for developing advanced methods to identify and differentiate between legitimate users and bots, such as analyzing headless browser font rendering. It's important to note that Anubis relies on modern JavaScript features, which can be disabled by plugins like JShelter, thus requiring users to disable such plugins for this domain.

This book treats the general theory of Poisson structures and integrable systems on affine varieties in a systematic way. Special attention is drawn to algebraic completely integrable systems. Several integrable systems are constructed and studied in detail and a few applications of integrable systems to algebraic geometry are worked out. In the second edition some of the concepts in Poisson geometry are clarified by introducting Poisson cohomology; the Mumford systems are constructed from the algebra of pseudo-differential operators, which clarifies their origin; a new explanation of the multi Hamiltonian structure of the Mumford systems is given by using the loop algebra of sl(2); and finally Goedesic flow on SO(4) is added to illustrate the linearizatin algorith and to give another application of integrable systems to algebraic geometry.
